No clear evidence yet when just looking at a small sample of UK data. It's clear from SA that this wave is having lower mortality than previous waves (perhaps for a mixture of reasons). There is also data that shows that Omicron spreads much slower in the lung than the previous variant, while spreading 70 times faster in bronchial tissue (which is why it is so transmissable) so there is a suspected vector for why it may be milder.
